KMeansLearner taking inordinately long

Hello,

I want to train a HMM with ObservationVector of size 9, sequence of size 5, 
sequeces of size 500 and no of states =10. 

example ObservationVector :
{1.377,10.0,0.0,301.5,1214.5685016666664,315203.6001666666,3.5076600116666667,20

The program virtually hangs after printing numberOfHiddenStates: 10.

please help.

            numberOfHiddenStates++;
        } while (Double.isNaN(trainedHmm.getPi(0)) && numberOfHiddenStates< 20);

        return trainedHmm;
    }
